SeeSaw is apps to communicate with friends with photos(There is a doodle function). Seemingly this looks like a copy of Snapchat, and most of its functions are the same. However, the big difference is photos deletion speed. SeeSaw deletes photos in a minimum period of 1 second. What can we confirm in only 1 second?! Furthermore, we can set photos watching time only 8 seconds even the longest. In the meantime, it is faster than Snapchat. May the Japanese discover the new communication using this?
